Veriskin is an American medical device startup developing a noninvasive skin cancer screening device. Based on a Qualcomm Snapdragon 410 processor, Veriskin’s handheld device is an innovative solution which determines whether a suspect skin growth is cancerous less than two minutes.
Veriskin’s skin cancer detection device is an advanced medical Wi-Fi enabled solution, utilizing all the capabilities of a FPGA (Field Programmable Gate Array) coupled with LEDs to detect skin condition with a simple scan.

While developing this innovative skin cancer screening device, Veriskin was seeking a partner with an extensive embedded Linux software expertise, combined with a strong experience on Qt graphical user interface development.

Witekio provided a complete set of software services to develop the technical solution. This set of services includes low level software development, from Board Support Package development, to boot-time improvement up to graphical user interface application development.
With regards to low level embedded development, Witekio managed to port and adapt a custom Linux Board Support Package on Veriskin’s device based Variscite System on Module Qualcomm Snapdragon 410. This Linux BSP supports the on-board hardware components of the System on Module (esp. connectivity features, such as Wi-FI).

These low level developments enable the end user to benefit from all the functionalities of a Linux operating system combined with the raw performance and perks of the Qualcomm processor.
The BSP adaptation includes the optimization of the Linux kernel to fully support the device’s screen, as well as a full set of drivers tests to ensure greater reliability of the equipment.

As a final step of software collaboration, Witekio ensured the device’s boot time improvement as well as the development of an attractive and innovative Qt5 user interface application, including the features and advantages of the Qt 5 graphical framework.
